introduce support for new ngff_cardem board

Browse Source 
This adds support for the new ngff_cardem board, a board that
basically combines a ngff breakout board with a built-in SIMtrace2.

Cardem works, but depending on the modem it might need a adjusted ATR to
ensure a lower baud  rate is used by the modem, high rates might lead
to weird power cycling of the card after a few transfers.

Trace was also tested and appears to work as expected.
